From: José Fonseca Date: Thu, 7 Apr 2011 18:15:55 +0000 (+0100) Subject: st/wgl: Prevent spurious framebuffer sizes when the window is minimized. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16d42af618aa6250bedc7e66e0e2c0b061cc6e99;p=mesa.git st/wgl: Prevent spurious framebuffer sizes when the window is minimized. When the window is minimized GetClientRect will return zeros. Instead of creating a 1x1 framebuffer, simply preserve the current window size, until the window is restored or maximized again. --- diff --git a/src/gallium/state_trackers/wgl/stw_framebuffer.c b/src/gallium/state_trackers/wgl/stw_framebuffer.c index 670e542cb4f..d8b1440a688 100644 --- a/src/gallium/state_trackers/wgl/stw_framebuffer.c +++ b/src/gallium/state_trackers/wgl/stw_framebuffer.c @@ -112,7 +112,7 @@ stw_framebuffer_release( static INLINE void stw_framebuffer_get_size( struct stw_framebuffer *fb ) { - unsigned width, height; + LONG width, height; RECT client_rect; RECT window_rect; POINT client_pos; @@ -126,10 +126,17 @@ stw_framebuffer_get_size( struct stw_framebuffer *fb ) width = client_rect.right - client_rect.left; height = client_rect.bottom - client_rect.top; - if(width < 1) - width = 1; - if(height < 1) - height = 1; + if (width <= 0 || height <= 0) { + /* + * When the window is minimized GetClientRect will return zeros.
